Climate controllers / thermostats should be possible to add to a ‘Climate Group Helper’ and control them simultaneously.
Use case:
I currently have six radiators with either Danfoss or Fibaro Thermostats controlling them. I often need to adjust them at the same time, to the same temperature target.
It would be really nice to be able to adjust the target temperature with just one action - weather it be manually or via automations in a group helper - just as I can with lights, fans, locks, etc.
